Ex-US special forces announced the creation of the AK-21 assault rifle - a weapon-grade hybrid AK-47 and AR-15

American veterans of the war in Afghanistan argue over which rifle weapon is the most optimal for conventional army and special units when they perform combat missions in this country.

Considering the fact that in Afghanistan itself they prefer Soviet / Russian small arms, the American army decided to a certain extent to study the experience of their combat use and use as a technological basis for creating a new version of weapons - on the one hand, unpretentious to use, on the other, accurate and powerful.
Thus, two former US Army Special Forces soldiers (2nd Ranger Battalion) Joe Stenzel and Jared Potter analyzed the merits and demerits of Soviet Kalashnikov assault rifles (AK-47, AK-74) and of American automatic and semi-automatic rifles, including the AR-15.

An article by Blake Stillwell was published in the American press, who writes that Stenzel and Potter decided to take advantage of their own experience in using Russian and American-made weapons and create something new that would absorb exclusively the advantages of the AK-47 and AR-15.

From the material about the enterprising ex-special forces:

After leaving the army, they decided that fixing these shortcomings could be the best post-war career for both of them. As a result, a modernized version of the AK-47 assault rifle - AK-21 from the new company Stenzel Industries appeared (by the name of one of those ex-special forces of the US Army - approx. "VO"). This is the first AK aluminum platform to hit the market, and is as robust in the field as the AK, but with the ease of use and manufacturability of the AR family.

For obvious reasons, there is no need to talk about any licensed production of such weapons by American "masters". In fact, we are talking about a violation of technological copyright for the creation of weapons belonging to a Russian concern. However, in the United States, such production and theft of intellectual property are considered quite normal.

Jared Potter:

The Russian Kalashnikov assault rifle is not as ergonomic as the AR and is not as easy to modify. But during our stay in Afghanistan, we realized that if the AK were to add ergonomics and modularity, it would be great.

As a result, a kind of weapon "hybrid" of AK and AR was created with a modular layout, which allows the use of various magazines and ammunition of different calibers. The main caliber is 7,62 mm.

Joe Stenzel:

We designed the AK-21 assault rifle to be versatile and easy to manufacture. Its parts, in principle, can be produced in any country.

The created version of the AK-21 has an aluminum platform. The US media write that this is the first aluminum platform of the Kalashnikov assault rifle to appear on the market. In other words, Stenzel and Potter do not hide that their main goal is to obtain financial gain. The retail price of the AK-21 has already been announced - $ 3999 on the domestic American market.

Described features and characteristics of the American "hybrid":

Aluminum alloy receiver, double-sided bolt, short-stroke system, fire mode switch and fuse for the M249 SAW light machine gun.

[loki565]

It can be produced in any country, only the quality will be different)))

[WHAT IS]

A copy is always worse than the original.

[figwam]

In combat conditions, there is no more reliable Kalashnikov! The whole world is suffering, including the United States, to create the same reliability.

[NIKN]

Quote: figvam

In combat conditions, there is no more reliable Kalashnikov!

This is a fact and precisely the absence of the mentioned improvements from the outside, because there is no way to improve the manufacturability of the AK. To stuff aluminum there ... something alarming here. Kalash is the ideal middle of the technology in which its fantastic reliability, worked out for decades, is possible, any step here or there will be to the detriment of something.
But I am now gnawing at the question of how the AK-21 stands. Are they trying to say that the Kalashnikov was invented?

[figwam]

Quote: NIKNN

how AK-21 stands for. Are they trying to say that the Kalashnikov was invented?

They just do not hesitate to use a world-famous brand, in the USA there is a great demand for AK, but the sale of our machine is prohibited there, there are sanctions, so the firms are trying to grab the dough by inventing fakes.

[ironic]

True? Sure?

[Herman 4223]

Judging by the huge gap in the receiver, which is not covered at all with anything, and even through, it is clearly worse.
Dirt, sand and anything else will get there.

[Free wind]

Made for left and right handers.

[Herman 4223]

And for the flies that will fly there. Because th ... a lot will get there.

[ironic]

That at least th .. but at least cakes. The main thing is that ventilation is sufficient and it is comfortable to grab.

[ironic]

Excuse me, but what will it interfere with? And the trunk is open for ventilation from all sides.

[Herman 4223]

What will be in the way? Well, I don't even know, because everyone knows that a little sand and dirt in a working mechanism is good.

[ironic]

So, as it were, sand and dirt is just always considered a lesser problem of this type of mechanism, and what is stuffed into the grasping holes there seems to be no problem at all, it will dry out, disappear by itself, or if it comes to leaving, it will be cleaned.

[loki565]

That at least th .. but at least cakes. The main thing is that ventilation is sufficient and it is comfortable to grab.

Such a forend is good at shooting ranges, in real combat conditions everything is much sadder))) There were cases when after a prone position and crawling, dust mixed with grass was stuffed in the forend and after several shots it all started to smoke and burn))) And it was funny to watch how great tacticians try to extinguish it and pick it out of the forearm)))

[Nosgoth]

Can you read? We are not talking about the fore-end, but about the through slot in the receiver (to be more precise, in the cover of the receiver), where the automatics are located. Or "who hurts ..."?

[loki565]

Can you read? We are not talking about the fore-end, but about the through slot in the receiver (to be more precise, in the cover of the receiver), where the automatics are located. Or "who hurts ..."?

This is your problem, since you cannot understand who and what they are writing)))

Excuse me, but what will it interfere with? And the barrel is open for ventilation from all sides

The cons of this receiver have already been written

[ironic]

Duc over there at Tavor, too, all sorts of holes in different versions are available and niche and in the mud and in the Golan any crap can not grow in spring and autumn at the most. And people are training right now.

[Herman 4223]

Your machine gun from the picture is also from Israel, maybe that's why they adore M-16 so much. Warrior uh from this site from her trudge. The cracks there are mostly covered.

[ironic]

No Alpha is supplied to Israel. And where is she M-16 today? Only shortened versions remain. M4 - yes, they love her. The regular ones are mostly Tavors.

[Herman 4223]

It is not delivered there, it is done there. About the M-16, I wrote that local commentators from Israel adore it, but whether they are running with it now or not, I cannot say. I saw a video of one Ukrainian soldier with the parsing of the fort machine gun (this is essentially
Tavor at 5,45), in his words, when he got to know this machine better, he did not cease to be upset that he did not fall into his hands earlier as his colleagues.

[ironic]

The good thing about the M-16 is that it is light and accurate, but the long version is uncomfortable. I just didn't run with her, but I traveled. It's good to shoot, but to ride or run ... well, it's not for nothing that they called it a broom in the IDF. What the Ukrainian military regrets, I did not understand, but in the IDF, in reality, now Tavor and M-4, and M-16 are being filmed.

[Herman 4223]

As far as I remember, he did not like this more complex design and more weight, something else, but it needs to be revised, I don’t remember so much.

[ironic]

~ 3 and a half kg? The long broom was 2.9. Kalash, if it is easier, it is cosmetically. And as for the complexity, these are the subtleties in which you need to dig.

[Herman 4223]

https://youtu.be/qY2XrEZ-0F0
I found this video.
He weighs under four kilos.

[ironic]

Galil has not been used for a long time, and for some reason the author still has him in the Israeli army. The heaviest version Tavor-21 weighs 3.67 kg, while the Ukrainians for some reason have 3.9. Galil weighed under 4.5 kg, and the machine gun that replaced him did not fulfill its task of being lighter. The author does not like the bullpup system at all and had to start with that. Some kind of reasoning about firing half a kilometer or more, especially from Kalash. In short, the rut is immeasurable. And then it turns out that the steep shooter does not succeed in shooting at 100m, but the mediocre shooter does everything better than usual. The store has been screwed up, and Tavor is to blame. M-4 short uses only special forces and it is clear why, there is no weight at all. Well, in short ...

[Herman 4223]

All the same, it is clear that a person is friends with this technique and uses it. The arch on the table, as I know, is personal. Looked at the characteristics of the Ukrainian version is really the heaviest. But 3,67 kg is also a good weight in the AK-74 weight 3.3kg 3.5kg AK-12. Why is there no rammer? This function is sometimes necessary.

[ironic]

I will not argue that Tavor is a wunderwaffle, but the initial negative attitude of the military immediately catches the eye, i.e. he is not impartial in his analysis. He himself admits that all the problems are with the 5.45 cartridge. I suppose that the story is the same with the rammer, there are no problems with 5.56, so they did not. They failed to establish high-quality production under the Soviet patron, and this is the whole secret. The weight of the AK may be less, but it is longer, with a shorter barrel and, by the way, has never been a weapon of high accuracy, especially in terms of the very sighting device that the analyst cites as an example. It is there generally removable in place with the entire lid, which is generally not buzzing. Well that is I do not believe him, there are too many obvious exaggerations.

[SASHA OLD]

the very top, this is the top-1: "Kalash" from the "tribal zone" - where I just got crazy with their production ...
Onokoy good fellow, he tells great story.

[rocket757]

They will put you on the table and don't steal !!!
Eh, if only it were so

[boni592807]

Or maybe easier? Stop, like China or the United States with other partners, messing with THEIR rights to their inventions. They have deeply and for a long time on our rights ... Otherwise, it turns out that we protect their rights on our territory (for example, for software, etc.), they receive NOT a small benefit from IT from Russia , on our rights in a brazen spit . Is it high time to actually be for EQUALITY ?!

[voyaka uh]

The term of a military patent is 10 years.

[Nadrub]

This makes us different from China

[Terran ghost]

they spit on our rights

What rights exactly? The maximum period of validity of a patent for ANY invention or utility model is 20-25 years. Simply put, any inventions or utility models created before December 31.12.1994, 17 inclusive (no matter - German, Chinese, Dutch, Japanese or from any other country) are in the world public domain. And this is how it should be. This is the essence of the "patent deal" as it has functioned since the XNUMXth century.

[dokusib]

Yes, there are no patents for the Kalashnikov system as a whole. So these guys are not breaking anything. An all-milled receiver cover is not bad, but it is more of a tuning and not something new, but why a butt with a recoil buffer is drawn in the pictures is a question. Apparently there were no others available, but Magpool probably patented his butt. In general, most likely they do not do anything new, but are engaged in tuning Kalash (replacing the receiver for Americans with their aper and lowers is tuning)

[General failure]

Aluminum alloy receiver, two-way shutter, system short stroke.

With such characteristics, there is only a name from AK.
From the pictures, only one thing is clear - it will use stores from AK.

As for the aluminum receiver, it certainly does not rust, but it is made by milling (i.e. expensive) and its strength is worse than that of steel.

[Captain Pushkin]

Quote: General Failure

As for the aluminum receiver, it certainly does not rust, but it is made by milling (i.e. expensive) and its strength is worse than that of steel.

The aluminum receiver can be made by casting, and its rigidity (resistance to bending and torsion) will be higher than that of stamped steel.
It will be, in any way, more expensive than AKM, but after all, they asked for a very high price.

[General failure]

Is that injection molding. But the equipment is even more expensive than for milling and does not at all negate the additional processing by milling.

That is, the same eggs, but in profile.

I think these peppers will not come to casting. This makes sense only for large-scale production, which does not exactly threaten this weapon freak.

[syndicalist]

But the heat sink is better

[General failure]

And if thermal paste is crammed into the aluminum receiver, the heat dissipation will be even better. Infa 100%.

It will be possible to blink the shutter "tactically" as much as you like, and the receiver will definitely not melt.

Two cunning burnouts decided to raise money without bothering with legality. XNUMX% Americans. Voryo.

They didn't even bother to come up with another name, AK-21. Those. they understand that AK is a brand, it is like a quality mark.

[General failure]

AK is not a brand, alas, because no one registered it, but it became common. And the American Chamber of Commerce does not register such a thing. For example, "Windows" is not a brand either.

Wait, the Kalashnikov concern in the American market sells weapons under the abbreviation "KR" - "Kalashnikov Rifle". I don't know if they registered it or not.

[Kurare]

As for the fact that AK is an "officially" unregistered brand - I agree. But, everyone knows what "Hey-Kay forti seven" is and what this name is tied to. Those. the name AK-21 is not taken from the ceiling, but precisely because A-Kay is a brand.

[SSR]

Quote: Kurare

AK-21

From AK they took AK and from Ar 12 they rearranged the numbers in places of 21 types crossed and got the AK-21.

[Kurare]

In fact, there is the AR-15, the founder of the line along which the army M-16 went further.

[Captain Pushkin]

Do you know at least one valid patent for an AK-47 or AKM?
I don’t.

[Simargl]

Quote: Stroibat stock

Vorie.

The question is who? Short shutter travel is towards AR. There is all that from the AK - the piston, but I think that the idea, rather, in the SVT is similar or like that of the HK G36.
Styling the case for AK, mounting the store, the store itself ...

[Reserve buildbat]

But does in this case there is a meaning - who has? Kalashnikov's, Stoner's ... It's just that this "product" is a compilation of other people's parts and ideas. No more.

[Simargl]

Quote: Stroibat stock

But does in this case there is a meaning - who has?

AR platform is freely available. The magazine and its mount from the AK and the gas piston from the G36 were screwed to it. Which of this is unprecedentedly patented?

[Reserve buildbat]

That is, if I take a Toyota Prius, stick an engine from a Cadillac de ville in there, call it a Toyota de ville mark 2 and sell it freely? Is it legal and beautiful?

[Free wind]

Yes, no one forbids, do it. There are a lot of examples. This is perfectly legal. The only thing that may be problems with the name. Courts often take place, and in our country. Especially among musicians who steal songs from each other, one note will be changed and they already think that this is another song. By the way mark -2 has not been produced for a long time.

[Reserve buildbat]

So I'm talking about that. Two burned out skolkhozili some kind of GMO, so as not to tell the truth, and call it as the Chinese with their abibas. Purely legally, there is nothing to complain about, but in fact it is a tattered thief.

[Terran ghost]

And no "thief" in fact.
Actually, on the good, any publicly expressed idea (including a publicly known technical invention or utility model), as well as published literary (text), musical work, and recently - also a drawing / photograph posted on the public segment of the Internet cannot be strictly in the sense of "belonging to someone" in the same sense in which a physical object can belong. Copying and borrowing is a normal, natural process for human civilization. That without which culture, technological progress and healthy market competition cannot exist.
Actually, as such, any copyright / patent rights are a kind of deal. The author / inventor receives, FOR TIME, exclusive rights (ie, a monopoly sanctioned by society) to the result of his work, in order to allow him to "recoup" spent expenses (in the form of direct financial costs and expenses of working time), and after this period, society enriches the precious luggage of the public domain vital for the development of culture and technology. The release of a work or invention into the public domain is no less important here than the concept of an exclusive right granted for a time.
PS: Actually, therefore, the current prohibitive duration of "copyright" is essentially a fundamental injustice from a moral and ethical point of view, serving only to enrich large and super-large capital (like the same Disney, RIAA and similar companies).

[Terran ghost]

Your company will not be able to call its product "Toyota". And for the rest - if the validity period of patents for the appearance of the car body and for the engine (the maximum validity period of patents in any case is 20-25 years) then yes you can. And in no case will this be any theft. Moreover, almost any innovation produced today includes once patented but released into the public domain or never patented inventions and technical solutions. No manufacturing company "reaches only with its own mind" without borrowing from digging sticks and stone axes to smartphones.

[Captain Pushkin]

But isn't the AK-47 and M16 a compilation of technical solutions already known at the time of development?

[Bad_gr]

Quote: Simargl

Short shutter travel is towards AR.

And the buffer in the direction of the butt of the machine sticks out, like hers.
Short piston stroke at SVD.
As for the preserved reliability of the Kalash, I very much doubt it.

[Herman 4223]

An interesting combination. But what does reliability have to do with it? Aluminum is easier to deform. This rifle will need to be handled more gently.

The price tag of 4 kilobax is a thick hint that this creation is focused on American casualrs.

[Cowbra]

Another bullshit. The return spring is again in the back of the tube, the piston is on top, so that it threw up - neither compactness, nor accuracy, nor reliability, all the worst were put together. A bolt on a spring protruding into the shoulder was woven into the luminous fixed frame - either a light bolt and goodbye to reliability, or a heavy bolt in a light frame - and give it to road builders instead of jackhammers. True, the road builder holding this miracle will sooner scatter than the asphalt

Better look at this - the piston ABOVE the bolt in front, the mainspring in the back, count from below. Lever that actually works to turn the shutter. Those. Normally, after the shot, it should not roll back, but recoat nafig in the frame and in the gas outlet.
Note - skew is when it is accidental, but here it is to skew

[three]

What are we discussing, dashing lads? An attempt by two old men to improve the AK again? The AK concern does not always succeed (or does not succeed) ... Essentially: the receiver? aluminum? So what ? Ergonomics? is it when the moment of recoil has increased and the accuracy, accuracy and so on flew? What are we discussing? (I had a lot of shooting - from Boers to dshk (there was a lot at the point), and Chinese and British, and Amersky (the Mauser with a butt made a great impression) ... banks "si-si" (the competition was won by the battalion commander, scolding and giving us snot)) ..

[Charik]

[paul3390]

Actually - with a high-quality cartridge, AKM-oids demonstrate quite a decent bunch. Checked. And the Russian Federation should do just that, improve the quality of gross army ammunition. And not rivet the next crafts like AK-12. Moreover, most of the bells and whistles are quite easy to put on regular copies. Only the lazy doesn’t make pribludy to AK ..

As for the creativity of amers-let alone run around with luminium weapons .. That was just not enough. I've seen enough of the results of operating similar solutions on the same Murka ..

[Terran ghost]

Actually - with a high-quality cartridge, AKM-oids demonstrate quite a decent bunch.

Likewise, with high quality AR15 / M16 cartridges, they demonstrate more than decent reliability in combat conditions. Those with "direct gas outlet". The "piston" variants (with a gas piston with a short stroke) demonstrate it, regardless of the quality of the cartridges. Plus, they do not have a specific problem of "runoff" army M4A1s with overheating during intense shooting.

running with luminous weapons

Depends on what kind of aluminum alloy and how it was processed. Aviation alloy T7075 is a very strong piece in this regard. But not the cheapest.

[Thrifty]

And how many shots of this miracle is enough? Aluminum, soft metal, deformation from overheating is in the order of things, a short piston stroke is a high probability of a cartridge skewing or jamming. And most importantly, where are our lawyers? Or, it's time to spit on the patent law, and go by the "Chinese method" - like it - copied, and respond to protests that world experience is used, and all products are similar to one degree or another! !!

[Free wind]

There is an alloy, and not remelted army spoons. I don't know where your lawyers are. If they are yours, then call them and give them an assignment.

Milling, as it is not very technological. For piece goods it will go, for mass production of haemorrhoids.

[paul3390]

Milling, as it is not very technological

Explosion stamping?

[Herman 4223]

A CNC milling machine works there.
Aluminum alloys are very easy to process, there will be no hemorrhoids.
Another thing is that the aluminum case is not the best solution for the machine.

[Dimide]

The most interesting thing is that all firms position their products as the reliability of the AK and the accuracy and ergonomics of the AR.
And AK Alfa and KS47, and the same ARAK 21

To skip is to recognize their homemade product.

However, in the United States, such production and theft of intellectual property are considered quite normal.

And in the United States since its inception, any theft is a normal phenomenon.
So, there is nothing to be surprised at.

the AK aluminum platform introduced to the market, and it is as reliable in the field as the AK, but it is also easy to use and manufacturabilitylike the AR family.

Judging by the photo with milled bolt frames, manufacturability was not close to a sim device !!!

[Maz]

Figase got the price high!

[yehat2]

a complete symbiosis of a hedgehog and a snake would be if they had made a 6.45 caliber - intermediate between 5.45 and 7.62. In general, the first full-fledged hybrid of technologies was in Israel (I don't remember what it was called), then the Americans did something, and the Germans made NK416 and it turned out to be very successful. I don't really understand what else you can think of.

[voyaka uh]

The Finns bought a license for AK from the USSR - created Valmet.
And Israel bought the license from Finland - created Galil.

Kalashnikov Israel LLC also acted on the basis of an officially acquired license. How things are going there now is not in the know. Have you heard anything new?

aluminum alloy-plus modern alloys of al steel are not much inferior and where is the modularity of the arch?

For obvious reasons, there is no need to talk about any licensed production of such weapons by American "masters". In fact, we are talking about a violation of technological copyright for the creation of weapons belonging to a Russian concern. However, in the United States, such production and theft of intellectual property are considered quite normal.
The classic illiterate dash of informational charity on the fan.
Firstly, there is no technological copyright, there is copyright, which does not apply to weapons, as well as the ideas, concepts, principles, methods, processes, systems, methods, solutions of technical, organizational and other problems related to them.

[Adler77]

A strange craft, in fact.
The Kalashnikov assault rifle is a mass army weapon for intense war in difficult conditions. It is simple and technologically advanced and reliable, accuracy suffers from this, but this is not critical for it, because. it is a soldier's weapon with little or no training.
It is unnecessary to make a high-precision complex out of Kalash, it will still lose, but it will rise in price and lose in reliability. Special weapons have been developed for special units. AK machine gun of the people's army.
And aluminum is of course nonsense. The barrel is then attached to the aluminum frame, it heats up very much, the structure will weaken at the attachment points and throw everything away.

"We decided to take advantage of our own experience in the use of Russian and American-made weapons and create something new that would take exclusively the advantages of the AK-47 and AR-15."
eh, if I were a citizen, I would not copy either one or the other, by the way, does anyone know what today can be copied worthwhile in a gas outlet automation?

[Rusnemez]

On the topic, let the lawyers deal with the issue of Rights to the product, but I personally would be interested to compare their version and AKV-521 from the Kalashnikov Concern.
A short stroke, and an AR system with a spring in the butt, how it will behave in real conditions. Luminescent parts, how much gain in weight?
It is clear that everyone will try for a long time to make something for those cartridges that are now, but I do not think that something much better will turn out than what we have today.
There is an idea that if you get new gunpowder, allowing you to reduce the cartridge itself in size, for example, fit the length of an automatic cartridge into the dimensions of a pistol caliber 6 mm. then this can give new products with less weight and dimensions, while retaining the military purpose.
Well, pistols for new powder-cartridges are more compact, using the gained weight-space for systems that reduce recoil.

[beeper]

The guys got an interesting design (for the Soviet cartridge 7,62-mm mod. 1943) (although I would have limited myself only to the "aper" and "lover", I would not make a separate receiver cover with such a general arrangement, but, m b. they had some kind of "commercial considerations" for the sale of "tuning parts" or constructive, technological "discrepancies" that could not be resolved by "swoop" and therefore made such an "additional" compromise ?!)!
In general, there is little information, only by the general appearance in the photo you can guess which locking system (Kalashnikov or Stoner) was used.
I am inclined to believe that, most likely, due to a set of advantages (which were analyzed in whole articles on the VO), a more reliable and efficient Kalashnikov locking system was used (and the corresponding shutter and bolt carrier, of course, without a piston rod, because They are, with a short stroke of the piston, separately, respectively, the general impulse of movement of the automation parts is also "crushed").
In principle, even looking at the photo (general and milled parts of the receiver, and its cover) and reading a short description of the design, the train of thought of these guys, in general, is clear and understandable to me.
Of course, there are still questions about heat dissipation. an alloy fore-end will quickly heat up (even this "ventilated") when firing, as well as become icy in the cold.
The barrel, the barrel bore, most likely, AR-ovsky (if the task is guaranteed to withstand three shots with water in the barrel was not set ?!), cut with a "tapestry" and chrome-plated ?!
The rollback buffer along the barrel axis was added correctly - it, just, will unload-damp the "duralumin" box from the Kalashnikov's guaranteed 5 m / s impact of the bolt carrier with the bolt at the end of the rollback.
CNC milling of parts made of aluminum alloys, in this case, is solved correctly - this is a modern trend in single and serial metalworking, as well as printing on a 3D printer (for mass production of "aluminum" receiver boxes, thin-walled injection molding is suitable, followed by a minimum amount of machining, starting as an aircraft designer, Eugene Stoner knew a lot about the use of such casting technologies ).
The configuration shown for the alloy receiver is well-designed and provides good rigidity for these parts!
The gas outlet is similar to an adjustable one and allows you to additionally "customize" the weapon.
I didn’t like the butt, it’s completely “raw”, it’s not well thought out to the end, and there’s no “cheekbone” either, for such a price the guys could (with their advertising motto “supposedly improve ergonomics” ) it is better to try to make the butt as it should - "hits the stock"!
The fire control handle is also so-so, the angle of inclination should be bent more, it is too straight for such a shape.
As a concept, this machine is not a bad idea, and there is still a lot to work on - to "lick" it constructively and technologically.

So after all, our Soviet "Kalash" in the form in which we know it now, was not immediately built, thousands of professional Soviet gunsmiths had to work hard on it: designers, technologists, testers and workers, and here there are only two amateur enthusiasts with combat experience and the desire to make your "best machine gun" (by compiling Kalashnikov and Stoner assault rifles) at the beginning of the journey!

The guys were late with their craft, the Kalashnikov Concern has already done everything!

Yes, and ours were late a long time ago, and what they blinded cannot be compared to any comparison:

Thanks to the Jews, they respected AK, retained their recognizability, significantly improving ergonomics and manufacturability.

[alexpro66]

Two amers at the expense of noodles want to cut down the dough, no more. Of everything that has been created on the basis of Kalash, the best aariant is Galil, especially the latest model. The Jews, due to the milled box, improved the ergonomics and kinematics of the shutter and increased the accuracy of shooting. Well, in the first place is our A-546 (762), I think it should be launched into a mass production and replace the Kalash, which is conservatively marking time.

[awdrgy]

First, luminescence, then plastic, then wood, and finally the top of manufacturability (and environmental friendliness) - pressed cardboard! (Specially processed-secret technologies) with a bunch of all kinds of damper gaskets and, most importantly, at a price of several thousand Baku ones! A good idea

[Grognag]

Personally, it is not entirely clear to me what the author, well, or the creators of the machine mean by hybrid and what does this hybrid mean?

[Terran ghost]

In fact, we are talking about a violation

The maximum term of validity of any patents for any inventions or utility models is no more than 20-25 years. After that, the invention becomes part of the global public domain. And this, in fact, is extremely useful and correct for all mankind.
Although in the case of the military-industrial complex, the observance of patent rights ... let's just say that they don't really bother at all. Tu-4 bomber ("nee" Boeing B-29 "Stratofortress") "sends heartfelt greetings." And next to it, the "Springfield M1903" rifle ("nee" - "Mauser arr. 1898") is flying a kiss.

double-sided valve, short stroke system

That is, their creation has nothing to do with AK. This is another variation on the AR18 automatic rifle by Eugene Stoner. Fortunately, the patents for it have long expired and there are a lot of options "on the topic". Although ... considering the "double-sided jam" I would not be surprised if at all it will end up as an almost exact copy of the FN SCAR assault rifle, only adapted for the 7,62x39mm cartridge and AK / AKM magazines.

Well, yes, for which royalties were paid to the Mauser company, for each rifle released, and at the same time a scandal happened when the royalty amount surfaced - it turned out that it was cheaper to initially buy a license from a Mauser than to create a rifle using the "reverse engineering" method and then pay.

As for patent protection, everything is not simple there and there are such a bunch of nuances starting from what is the object of protection - an invention, utility model or industrial design and ending with the terms of renewal in each specific organization and, accordingly, in those countries that are part of it. Many industrial designs of equipment from the 70s are still protected by American patents - it is banal because they are still being produced and the copyright holder extends the terms of protection on this basis. With the AK, the issue of patents does not roll at all, because they were not there when, and actually there is not much to patent there, the copyright certificate was issued by the ITC was issued only in the 90s and only for individual structural elements, but in fact, no protective force is it did not have.

[Terran ghost]

Well, yes, for which they paid royalties to the Mauser firm

Paid. But exactly because
a) "Mauser" received a patent in the USA
b) the design patent of 1898 was still valid in 1903.
And not "for each unit", but a fixed amount of $ 250.

Many industrial designs of equipment of the 70s are still protected by American patents - it is banal because they are still produced and the copyright holder, on this basis, extends the terms of protection

No US patents issued in the 1970s are currently valid. They all expired with no options.
US patents have a 20-year limit. After that, the invention / utility model / industrial design goes into the public domain, regardless of the "wishes" of the former patent holder and whether he still manufactures a product previously protected by a patent.
And yes, this is a fundamental point and only thanks to this there is generally technical progress as such and competition between different manufacturing firms.

[Terran ghost]

it turned out that it was cheaper to buy a license initially

By the way, in some cases, when it comes to particularly technically complex products (for example, aviation of the same), it is really much easier and cheaper to buy a license than to try to reproduce the product by reverse engineering.

[Siberian_54]

I quote: "For obvious reasons, there is no need to talk about any licensed production of such weapons by American" masters ". In fact, we are talking about a violation of technological copyright for the creation of weapons belonging to the Russian concern.".
Perhaps the author of the article will be interested to know that Kalashnikov M.T. there was no patent for the AK design. Accordingly, the KK concern does not have a patent for its design. If in doubt, study the patent base of Rospatent.
The reason is that the AK design is a compilation of previously known technical solutions. There was nothing to patent in essence. The layout, the automation scheme, the shutter, the USM - all this was invented before and has already been used on other weapons. And even if there was even such a patent, then since the 40s of the last century it would have long since lost its protection and become open for free use. Therefore, there is really no need to talk about any licensed production of AK.

The international patent protection terms are the same. Nobody can prolong it indefinitely. The invention is 25 years old - that's all. A trademark can be renewed for as long as you like. But there is such a thing as "authorship". It concerns design, appearance. Not to be confused with a promotional sample. The authorship of the appearance can be proven and it lasts as long as you like.

Quote: Adler77

A strange craft, in fact.
The Kalashnikov assault rifle is a mass army weapon for intense war in difficult conditions. It is simple and technologically advanced and reliable.

Have you seen the AK bolt head and frame? This is a spatial milled part. Try to make such details on your knee. Who spreads rumors that AK is technologically advanced and simple? PPSh and PPS were simple and technologically advanced. But this is not about AK.

[Armen Sologyan]

If we recall the "newbie" stolen by the Americans in the 90s and the attempt to use it, then we can say that the United States cannot copy Russian technologies because a maximum of 2 people died from the copied "newbie", and if there was a real Russian one, it was would a fucking bogeyman to all of them !!! And as for Our Kalashnikov, they will do better than Our Kalashnikov, and there will be some kind of pathetic parody of Kalashnikov !!!

The descendants of crooks cannot be honest people in fact, and if they are, this is an anomaly for the West-United States that is burned out by the hot iron of the Congress and the Senate.
Navar at any cost on any topic and in any field.
So nothing new in life. And we could cram aluminum and put the telescope on!

[Dmitry Vladimirovich]

In fact, we are talking about a violation of technological copyright for the creation of weapons,

Is not it? The frame is different, the shutter is different, the compensator in the rear wall of the receiver is secondary from the original: the layout and some technical solutions.

Another thing is that the decision is amateurish - a compilation of other people's solutions.
Centering the receiver cover is a primitive solution.
Durability is questionable (since the aluminum alloy of the receiver)
Manufacturability - goodbye (no stamping ...)

[the47th]

Judging by the pictures, this is an "AK type" with an aluminum receiver, a strange butt (I don't understand at all shoving a cylindrical guide everywhere except AR). Even a removable barrel, it seems, will not be.

And how do you like this descendant of the SVD?
